Use the laws of set algebra (that is, set identities)
RTP: A - (B ∩ C) = (A - B) U (A - C) . Use the laws of set algebra (that is, set identities)?
1) I changed the minus's
the rule is X-YZ = X*Y' + X*Z' (i dont use union or intersection, unions are + intersections are *)
So the left of the equation is now
A*B' + A*C' You can even draw a 3 peice venn diagram to see this
Now you can do the same for the right side
(A-B)+(A-C) = A*B' + A*C'
And you see they are equal
